## Architecture Overview
|
||||
|
||||
### Four-Tier Evidence Collection
|
||||
|
||||
```
|
||||
Tier 1: Distro Advisories (Confidence: 0.98)
|
||||
└─> Query: IDistroAdvisoryRepository.FindByCveAndPackageAsync()
|
||||
└─> Evidence: DSA/RHSA/USN with fixed_version metadata
|
||||
|
||||
Tier 2: Changelog Mentions (Confidence: 0.80)
|
||||
└─> Query: ISourceArtifactRepository.FindChangelogsByCveAsync()
|
||||
└─> Evidence: debian/changelog, RPM %changelog with CVE mentions
|
||||
|
||||
Tier 3: Patch Headers + HunkSig (Confidence: 0.85-0.90)
|
||||
└─> Query: IPatchRepository.FindPatchHeadersByCveAsync()
|
||||
└─> Evidence: Git commit messages, patch file headers, HunkSig matches
|
||||
|
||||
Tier 4: Binary Fingerprints (Confidence: 0.55-0.85)
|
||||
└─> Query: IPatchRepository.FindBinaryFingerprintsByCveAsync()
|
||||
└─> Evidence: TLSH locality hashes, instruction sequence hashes
|
||||
```
|
||||
|
||||
### Confidence Aggregation
|
||||
|
||||
```csharp
|
||||
Aggregate Confidence = max(baseConfidence) + multiSourceBonus
|
||||
|
||||
Multi-Source Bonus:
|
||||
- 2 tiers: +0.05
|
||||
- 3 tiers: +0.08
|
||||
- 4 tiers: +0.10
|
||||
|
||||
Example:
|
||||
- Tier 1 (0.98) + Tier 3 (0.85) = max(0.98) + 0.05 = 1.03 → capped at 0.98
|
||||
- Tier 2 (0.80) + Tier 3 (0.85) + Tier 4 (0.75) = 0.85 + 0.08 = 0.93
|
||||
```
|
||||
|
||||
### Proof Generation Workflow

|
||||
|
||||
## Handoff Notes
|
||||
|
||||
### For Storage Team
|
||||
1. **Implement Repository Interfaces:** See `BackportProofService.cs` lines 275-290 for interface definitions
|
||||
2. **Deploy Database Schema:** SQL schema provided in "Database Schema" section above
|
||||
3. **Seed Test Data:** Recommend seeding 100 CVEs across all tiers for integration testing
|
||||
4. **Performance Tuning:** Add indices on `(cve_id, package_purl)` for fast lookups
|
||||
|
||||
### For QA Team
|
||||
1. **Test Data Requirements:** Need sample advisories, changelogs, patches, binaries for each tier
|
||||
2. **Test Scenarios:**
|
||||
- Single-tier evidence (Tier 1 only, Tier 2 only, etc.)
|
||||
- Multi-tier evidence (Tier 1+3, Tier 2+3+4, all tiers)
|
||||
- No evidence (fallback to unknown proof)
|
||||
- High-volume batch processing (1000+ CVEs)
|
||||
3. **Validation:** Verify proof hashes are deterministic across runs
|
||||
|
||||
### For DevOps Team
|
||||
1. **Binary Storage:** Fingerprinting requires binary artifact storage (MinIO or S3-compatible)
|
||||
2. **Resource Sizing:** Proof generation is CPU-bound (SHA-256/BLAKE3), recommend 2+ vCPUs per worker
|
||||
3. **Caching Strategy:** Consider Redis cache for frequently-accessed proofs (TTL: 24h)
|
||||
|
||||
### For Security Team
|
||||
1. **Threat Model:** Proof tampering mitigated by cryptographic hashes (BLAKE3-256)
|
||||
2. **Evidence Authenticity:** Trust distro advisories (HTTPS + signature verification)
|
||||
3. **Key Management:** Proof signing keys should be rotated quarterly (recommend Vault integration)
|
||||

||||
We ship containers. We need:
|
||||
- **Authenticity & integrity** of build artifacts and metadata.
|
||||
- **Provenance** attached to artifacts, not platforms.
|
||||
- **Transparency** to detect tampering and retroactive edits.
|
||||
- **Determinism & explainability** so scanner judgments can be replayed and justified.
|
||||
- **Actionability** to separate theoretical from exploitable risk (VEX).
|
||||
- **Minimal trust** across multi‑tenant and third‑party boundaries.
|
||||
|
||||
**Non‑goals:** Building a new package manager, inventing new SBOM/attestation formats, or depending on closed standards.

````
|
||||
|
||||
**Adopted standards (pinned for interoperability):**
|
||||
|
||||
* **SBOM:** CycloneDX **1.7** (JSON/XML; 1.6 accepted for ingest)
|
||||
* **Attestation & signing:** **in‑toto Attestations** (Statement + Predicate) in **DSSE** envelopes
|
||||
* **Transparency:** **Sigstore Rekor** (inclusion proofs, monitoring)
|
||||
* **Exploitability:** **OpenVEX** (statuses & justifications)
|
||||
* **Modeling & interop:** **SPDX 3.0.1** (relationships / VEX modeling)
|
||||
* **Findings interchange (optional):** SARIF for analyzer output
|
||||
|
||||
> Pinnings are *policy*, not claims about “latest”. We may update pins via normal change control.
|
||||
|
||||
---
|
||||
|
||||
## 3) Security Invariants (What MUST Always Hold)
|
||||
|
||||
1. **Artifact identity is content‑addressed.**
|
||||
|
||||
* All identities are SHA‑256 digests of immutable blobs (images, SBOMs, attestations).
|
||||
2. **Every SBOM is signed.**
|
||||
|
||||
* SBOMs MUST be wrapped in **in‑toto DSSE** attestations tied to the container digest.
|
||||
3. **Provenance is attached, not implied.**
|
||||
|
||||
* Build metadata (who/where/how) MUST ride as attestations linked by digest.
|
||||
4. **Transparency FIRST mindset.**
|
||||
|
||||
* Signatures/attestations SHOULD be logged to **Rekor** and store inclusion proofs.
|
||||
5. **Determinism & replay.**
|
||||
|
||||
* Scans MUST be reproducible given: input digests, scanner version, DB snapshot, and config.
|
||||
6. **Explainability.**
|
||||
|
||||
* Findings MUST show the *why*: package → file path → call‑stack / entrypoint (when available).
|
||||
7. **Exploitability over enumeration.**
|
||||
|
||||
* Risk MUST be communicated via **VEX** (OpenVEX), including **under_investigation** where appropriate.
|
||||
8. **Least privilege & minimal trust.**
|
||||
|
||||
* Build keys are short‑lived; scanners run on ephemeral, least‑privileged workers.
|
||||
9. **Air‑gap friendly.**
|
||||
|
||||
* Mirrors for vuln DBs and containers; all verification MUST work without public egress.
|
||||
10. **No hidden blockers.**
|
||||
|
||||
* Policy gates MUST be code‑reviewable (e.g., Rego) and auditable; waivers are attestations, not emails.

* **Build/CI:** Holds signing capability (short‑lived keys or keyless signing).
|
||||
* **Registry:** Source of truth for image bytes; access via digest only.
|
||||
* **Scanner Pool:** Ephemeral nodes; content‑addressed caches; no shared mutable state.
|
||||
* **Artifacts Store:** Immutable, WORM‑like storage for SBOMs, attestations, proofs, SARIF, VEX.

|

|
||||
## 5) Data & Evidence We Persist
|
||||
|
||||
| Artifact | MUST Persist | Why |
|
||||
| -------------------- | ------------------------------------ | ---------------------------- |
|
||||
| SBOM (CycloneDX 1.7) | Raw file + DSSE attestation | Reproducibility, audit |
|
||||
| in‑toto Statement | Full JSON | Traceability |
|
||||
| Rekor entry | UUID + inclusion proof | Tamper‑evidence |
|
||||
| Scanner output | SARIF + raw notes | Triage & tooling interop |
|
||||
| VEX | OpenVEX + links to findings | Noise reduction & compliance |
|
||||
| Policy decisions | Input set + decision + rule versions | Governance & forensics |
|
||||
|
||||
Retention follows our Compliance policy; default **≥ 18 months**.
|
||||
|
||||
---
|
||||
|
||||
## 6) Scanner Requirements (Determinism & Explainability)
|
||||
|
||||
* **Inputs pinned:** image digest(s), SBOM(s), scanner version, vuln DB snapshot date, config hash.
|
||||
* **Explainability:** show file paths, package coords (e.g., purl), and—when possible—**entry‑trace/call‑stack** from executable entrypoints to vulnerable symbol(s).
|
||||
* **Caching:** content‑addressed per‑layer & per‑ecosystem caches; warming does not change decisions.
|
||||
* **Unknowns:** output **under_investigation** where exploitability is not yet known; roll into VEX.
|
||||
* **Interchange:** emit **SARIF** for IDE and pipeline consumption (optional but recommended).
|
||||
|
||||

|
||||
|
||||
## 7) Policy Gate (OPA/Rego) — Examples
|
||||
|
||||
> Gate runs after scan + VEX merge. It treats VEX as first‑class input.
|
||||
|
||||
### 7.1 Deny unreconciled criticals that are exploitable
|
||||
|
||||
```rego
|
||||
package stella.policy
|
||||
|
||||
default allow := false
|
||||
|
||||
exploitable(v) {
|
||||
v.severity == "CRITICAL"
|
||||
v.exploitability == "affected"
|
||||
}
|
||||
|
||||
allow {
|
||||
not exploitable_some
|
||||
}
|
||||
|
||||
exploitable_some {
|
||||
some v in input.findings
|
||||
exploitable(v)
|
||||
not waived(v.id)
|
||||
}
|
||||
|
||||
waived(id) {
|
||||
some w in input.vex
|
||||
w.vuln_id == id
|
||||
w.status == "not_affected"
|
||||
w.justification != ""
|
||||
}
|
||||
```
|
||||
|
||||
### 7.2 Require Rekor inclusion for attestations
|
||||
|
||||
```rego
|
||||
package stella.policy
|
||||
|
||||
violation[msg] {
|
||||
some a in input.attestations
|
||||
not a.rekor.inclusion_proof
|
||||
msg := sprintf("Attestation %s lacks Rekor inclusion proof", [a.id])
|
||||
}
|
||||
```

## 9) Minimal CLI Playbook (Illustrative)
|
||||
|
||||
> Commands below are illustrative; wire them into CI with short‑lived credentials.
|
||||
|
||||
```bash
|
||||
# 1) Produce SBOM (CycloneDX 1.7) from image digest
|
||||

|
||||
# 2) Create in‑toto DSSE attestation bound to the image digest

## 10) JSON Skeletons (Copy‑Ready)
|
||||
|
||||
### 10.1 in‑toto Statement (DSSE payload)
|
||||
|
||||
```json
|
||||
{
|
||||
"_type": "https://in-toto.io/Statement/v1",
|
||||

|
||||
{
|
||||

|
||||
"digest": { "sha256": "IMAGE_DIGEST_SHA256" }
|
||||

|
||||
"predicateType": "https://stella-ops.org/attestations/sbom/1",

|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 10.2 DSSE Envelope (wrapping the Statement)

||||
"keyid": "KEY_ID_OR_CERT_ID",
|
||||
"sig": "BASE64URL_SIGNATURE"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### 10.3 OpenVEX (compact)
|
||||
|
||||
```json
|
||||
{
|
||||
"@context": "https://openvex.dev/ns/v0.2.0",
|
||||
"author": "Stella Ops Security",
|
||||
"timestamp": "2025-10-29T00:00:00Z",
|
||||
"statements": [
|
||||
{
|
||||
"vulnerability": "CVE-2025-0001",
|
||||
"products": ["pkg:purl/example@1.2.3?arch=amd64"],
|
||||
"status": "under_investigation",
|
||||
"justification": "analysis_ongoing",
|
||||
"timestamp": "2025-10-29T00:00:00Z"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 11) Handling “Unknowns” & Noise
|
||||
|
||||
* Use **OpenVEX** statuses: `affected`, `not_affected`, `fixed`, `under_investigation`.
|
||||
* Prefer **justifications** over free‑text.
|
||||
* Time‑bound **waivers** are modeled as VEX with `not_affected` + justification or `affected` + compensating controls.
|
||||
* Dashboards MUST surface counts separately for `under_investigation` so risk is visible.
|
||||
|
||||
---
|
||||
|
||||
## 12) Operational Guidance
|
||||
|
||||
**Key management**
|
||||
|
||||
* Use **ephemeral OIDC** or short‑lived keys (HSM/KMS bound).
|
||||
* Rotate signer identities at least quarterly; no shared long‑term keys in CI.
|
||||
|
||||
**Caching & performance**
|
||||
|
||||
* Layer caches keyed by digest + analyzer version.
|
||||
* Pre‑warm vuln DB snapshots; mirror into air‑gapped envs.
|
||||
|
||||
**Multi‑tenancy**
|
||||
|
||||
* Strict tenant isolation for storage and compute.
|
||||
* Rate‑limit and bound memory/CPU per scan job.
|
||||
|
||||
**Auditing**
|
||||
|
||||
* Every decision is a record: inputs, versions, rule commit, actor, result.
|
||||
* Preserve Rekor inclusion proofs with the attestation record.
|
||||
|
||||
---
|
||||
|
||||
## 13) Exceptions Process (Break‑glass)
|
||||
|
||||
1. Open a tracked exception with: artifact digest, CVE(s), business justification, expiry.
|
||||
2. Generate VEX entry reflecting the exception (`not_affected` with justification or `affected` with compensating controls).
|
||||
3. Merge into policy inputs; **policy MUST read VEX**, not tickets.
|
||||
4. Re‑review before expiry; exceptions cannot auto‑renew.
|
||||
|
||||
---
|
||||
|
||||
## 14) Threat Model (Abbreviated)
|
||||
|
||||
* **Tampering**: modified SBOMs/attestations → mitigated by DSSE + Rekor + WORM storage.
|
||||
* **Confused deputy**: scanning a different image → mitigated by digest‑only pulls and subject digests in attestations.
|
||||
* **TOCTOU / re‑tagging**: registry tags drift → mitigated by digest pinning everywhere.
|
||||
* **Scanner poisoning**: unpinned DBs → mitigated by snapshotting and recording version/date.
|
||||
* **Key compromise**: long‑lived CI keys → mitigated by OIDC keyless or short‑lived KMS keys.
|
||||
|
||||
---
|
||||
|
||||
## 15) Implementation Checklist
|
||||
|
||||
* [ ] SBOM producer emits CycloneDX 1.7; bound to image digest.
|
||||
* [ ] in‑toto+DSSE signing wired in CI; Rekor logging enabled.
|
||||
* [ ] Durable artifact store with WORM semantics.
|
||||
* [ ] Scanner produces explainable findings; SARIF optional.
|
||||
* [ ] OpenVEX emitted and archived; linked to findings & image.
|
||||
* [ ] Policy gate enforced; waivers modeled as VEX; decisions logged.
|
||||
* [ ] Air‑gap mirrors for registry and vuln DBs.
|
||||
* [ ] Runbooks for key rotation, Rekor outage, and database rollback.
|
||||
|
||||
---
|
||||
|
||||
## 16) Glossary
|
||||
|
||||
* **SBOM**: Software Bill of Materials describing packages/components within an artifact.
|
||||
* **Attestation**: Signed statement binding facts (predicate) to a subject (artifact) using in‑toto.
|
||||
* **DSSE**: Envelope that signs the canonical payload detached from transport.
|
||||
* **Transparency Log**: Append‑only log (e.g., Rekor) giving inclusion and temporal proofs.
|
||||
* **VEX**: Vulnerability Exploitability eXchange expressing exploitability status & justification.

## 9) Moats
|
||||
|
||||
<!-- TODO: Review for separate approval - updated moats section -->
|
||||
**Four capabilities no competitor offers together:**
|
||||
|
||||
1. **Signed Reachability** – Every reachability graph is sealed with DSSE; optional edge-bundle attestations for runtime/init/contested paths.
|
||||
2. **Deterministic Replay** – Scans run bit-for-bit identical from frozen feeds and analyzer manifests.
|
||||
3. **Explainable Policy (Lattice VEX)** – Evidence-linked VEX decisions with explicit "Unknown" state handling.
|
||||
4. **Sovereign + Offline Operation** – FIPS/eIDAS/GOST/SM/PQC profiles and offline mirrors as first-class toggles.
|
||||
|
||||
**Decision Capsules:** Every scan result is sealed in a Decision Capsule—a content-addressed bundle containing exact SBOM, vuln feed snapshots, reachability evidence, policy version, derived VEX, and signatures. Auditors can re-run any capsule bit-for-bit to verify the outcome.
|
||||
|
||||
**Additional moat details:**
|
||||
- **Deterministic replay:** Hash-stable scans with frozen feeds and analyzer manifests; replay packs verifiable offline.
|
||||
- **Hybrid reachability attestations:** Graph-level DSSE always; selective edge-bundle DSSE for runtime/init/contested edges with Rekor caps. Both static call-graph edges and runtime-derived edges can be attested.
|
||||
- **Lattice VEX engine (Evidence-Linked):** Trust algebra across advisories, runtime, reachability, waivers; explainable paths with proof-linked decisions. Unlike yes/no approaches, explicit "Unknown" state handling ensures incomplete data never leads to false safety.
|
||||
- **Crypto sovereignty:** FIPS/eIDAS/GOST/SM/PQC profiles and offline mirrors as first-class configuration.
|
||||
- **Proof graph:** DSSE + Rekor spanning SBOM, call-graph, VEX, Decision Capsules, replay manifests for chain-of-custody evidence.
|
||||
- **VEX Propagation:** Generate vulnerability status attestations downstream consumers can automatically trust and ingest—scalable VEX sharing across the supply chain.

# StellaOps Moat Track — Spec Outline v0.5
|
||||
|
||||
> **Core Thesis:** Stella Ops isn't a scanner that outputs findings. It's a platform that outputs **attestable decisions that can be replayed**. That difference survives auditors, regulators, and supply-chain propagation.
|
||||
|
||||
---
|
||||
|
||||
## The Category Difference
|
||||
|
||||
Traditional scanners output findings: "CVE-2024-1234 exists in package X."
|
||||
|
||||
Stella Ops outputs decisions: "CVE-2024-1234 is reachable via this call path, vendor VEX says not_affected but runtime disagrees (creating a conflict the policy must resolve), and here's the signed proof chain."
|
||||
|
||||
This isn't a feature gap—it's a category difference.
|
||||

## Why Competitors Can't Easily Catch Up
|
||||
|
||||
| Origin | Representatives | What They Optimized For | Architectural Constraint |
|
||||
|--------|----------------|------------------------|--------------------------|
|
||||
| **Package Scanners** | Trivy, Syft/Grype | Fast CLI, broad coverage | No forensic reproducibility; VEX is boolean; no DSSE for reachability |
|
||||
| **Developer UX** | Snyk | IDE integration, fix PRs | SaaS-only; no attestation infrastructure; offline impossible |
|
||||
| **Policy/Compliance** | Prisma, Aqua | Runtime protection, CNAPP | No deterministic replay; no cryptographic provenance |
|
||||
| **SBOM Operations** | Anchore | SBOM storage, lifecycle | No lattice VEX; no signed reachability; no regional crypto |
|
||||
|
||||
Retrofitting our capabilities requires fundamental rearchitecture—not just features.

## Four Capabilities No Competitor Offers Together
|
||||
|
||||
| # | Capability | What It Is | Why It's Hard to Copy |
|
||||
|---|-----------|-----------|----------------------|
|
||||
| 1 | **Signed Reachability** | Every reachability graph sealed with DSSE; optional edge-bundle attestations for runtime/init/contested paths. Hybrid static + runtime. | Requires three-layer instrumentation + cryptographic binding to call paths |
|
||||
| 2 | **Deterministic Replay** | Scans run bit-for-bit identical from frozen feeds and analyzer manifests. Decision Capsules seal all evidence. | Requires content-addressed evidence model + feed snapshotting + deterministic ordering |
|
||||
| 3 | **Explainable Policy (K4 Lattice VEX)** | Belnap K4 logic (Unknown/True/False/Conflict) merges SBOM, advisories, VEX, waivers into single verdict with proof links. | Requires rethinking VEX from suppression to logical claims |
|
||||
| 4 | **Sovereign + Offline Operation** | FIPS/eIDAS/GOST/SM/PQC profiles as config toggles. Sealed knowledge snapshots for air-gap parity. | Requires pluggable crypto + offline trust roots + regional compliance |
|
||||
|
||||
**Scope of this doc:**
|
||||
(1) Decision Capsules, (2) Deterministic Replayable Scans (SRM), (3) Policy Engine & Lattice UI, (4) Sovereign Readiness (CryptoProfile + RootPack), (5) Attestation Observability Graph (AOG), (6) Procurement‑Grade Trust Statement, (7) Third‑Party Proof Channel, (8) Zastava differential SBOM + AI scheduler.
|
||||
|
||||
Cross‑cutting principles: offline‑first, cryptographic determinism, evidence‑bound decisions, regional crypto compliance, minimal operational friction.
|
||||
|
||||
---
|
||||
|
||||
## 0) Shared Concepts (applies to all 8)
|
||||
|
||||
* **Artifact identity:** digest-first (OCI image digest, file sha256).
|
||||
* **Canonicalization:** all structured payloads (SBOM, SRM, Trust Statement JSON, VEX) are normalized via Canonical JSON (RFC‑8785‑like) prior to hashing/signing.
|
||||
* **Signatures:** DSSE envelopes; **dual‑signing** supported (e.g., FIPS ECDSA + GOST R 34.10; or ECDSA + SM2).
|
||||
* **Attestation chain:** each decision (scan, VEX merge, policy evaluation) yields a signed, replayable record.
|
||||
* **Profiles & Packs:** **CryptoProfile** (algorithm + root policy) and **RootPack** (trust anchors + OCSP/CRL/TSA mirrors) are versioned and importable.
|
||||
* **Policy Unit Tests:** any policy/lattice bundle ships with fixtures expected to pass during CI.
|
||||
|
||||

|
||||
|
||||
## 1) Deterministic Replayable Scans — SRM
|
||||
|
||||
### Objective
|
||||
|
||||
Make every scan a **provable, re‑executable fact**. Auditors can replay; results are bit‑for‑bit reproducible.
|
||||
|
||||
### Deliverables
|
||||
|
||||
* **SRM v0.1** schema (YAML/JSON)
|
||||
* Deterministic executor + `stella replay`
|
||||
* Replay diffing and result hashing
|
||||
|
||||
### SRM (Stella Replay Manifest) — schema (abridged)

|
||||
rekor: { entries: ["<uuid>", ...] } # optional (offline allowed)
|
||||
```
|
||||
|
||||
### CLI & API
|
||||
|
||||
* `stella scan --image reg/app@sha256:... --srm-out srm.yaml --findings findings.json`
|
||||
* `stella replay srm.yaml --out replay.json --assert-digest <sha>`
|
||||
* `POST /v1/srm/replay` → returns `ok`, `replay_report_digest`, `diff` (if any).
|
||||
|
||||
### Determinism Rules
|
||||
|
||||
* Single thread or ordered parallel with stable scheduling; sorted inputs; fixed random seed; pinned rules/feeds/policies from SRM; identical canonicalization routines.
|
||||
|
||||
### Acceptance Criteria
|
||||
|
||||
* Replaying SRM on a different host returns identical `report_digest`.
|
||||
* If any feed archive differs by 1 bit, replay fails with a precise diff.
|
||||
* SRM size ≤ 25 MB for a typical microservice image (excludes large feed archives, which may be referenced by digest and bundled as a side‑car tar).
|
||||

|
||||
|
||||
## 2) Policy Engine & Lattice UI
|
||||
|
||||
### Objective
|
||||
|
||||
Turn VEX merging and severity logic into **programmable, testable algebra** with explainability.
|
||||
|
||||
### Trust Algebra Foundation (Implemented 2025-12)
|
||||
|
||||
The lattice engine uses **Belnap K4 four-valued logic** to aggregate heterogeneous security claims:
|
||||
|
||||
* **K4 Values**: Unknown (⊥), True (T), False (F), Conflict (⊤)
|
||||
* **Security Atoms**: Six orthogonal propositions per Subject:
|
||||
- PRESENT: component instance exists in artifact
|
||||
- APPLIES: vulnerability applies to component (version match)
|
||||
- REACHABLE: vulnerable code reachable from entrypoint
|
||||
- MITIGATED: controls prevent exploitation
|
||||
- FIXED: remediation applied
|
||||
- MISATTRIBUTED: false positive indicator
|
||||
|
||||
* **Claim Resolution**: Multiple VEX sources (CycloneDX, OpenVEX, CSAF) normalized to atoms, aggregated with conflict detection, then disposition selected via priority rules.
|
||||
* **Implementation**: `src/Policy/__Libraries/StellaOps.Policy/TrustLattice/` (110 tests passing)
|
||||
|
||||
### Model
|
||||
|
||||
* **Domain:** partial order over vulnerability states:
|
||||
`unknown < under_investigation < affected || not_affected < fixed`.
|
||||
Cross‑product with *scope*: `{runtime_path, build_path, optional_path}` and *confidence*: `{low, med, high}`.
|
||||
* **Merge semantics:** monotonic lattice joins; conflict resolution rules prioritized by signed source trust and policy precedence.
|
||||
|
||||
### DSL (sketch)
|
||||
|
||||
```hocon
|
||||
policy "corp-runtime" version "2025.08.15" {
|
||||
sources {
|
||||
trust_order = ["vendor:redhat", "internal:appsec", "public:nvd"]
|
||||
require_signatures = true
|
||||
}
|
||||
|
||||
rules {
|
||||
when vex.statement == "not_affected"
|
||||
and evidence.entrypoint_exposes == false
|
||||
then state := not_affected with confidence := high;
|
||||
|
||||
when package.is_dev_dependency == true
|
||||
then scope := optional_path;
|
||||
|
||||
when cvss >= 9.0 and reachable == true
|
||||
then priority := "block";
|
||||
}
|
||||
|
||||
guards {
|
||||
forbid unsigned_sources;
|
||||
forbid downgrade_of_state_below previous_state;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### UI (“Trust Algebra Studio”)
|
||||
|
||||
* Drag‑and‑drop rule blocks, precedence editor, **simulation mode** on sample SBOM/VEX; **policy unit tests**.
|
||||
* Export **signed** `.lattice.json`; importable into CI.
|
||||
|
||||
### CLI & API
|
||||
|
||||
* `stella policy lint corp-runtime.lattice.json`
|
||||
* `stella policy test --fixtures fixtures/`
|
||||
* `POST /v1/policy/evaluate` → normalized decision + proof trail.
|
||||
|
||||
### Acceptance Criteria
|
||||
|
||||
* Given same inputs, policy evaluation yields identical decision + proof trail hash.
|
||||
* UI can round‑trip DSL ⇄ JSON with no semantic drift.
|
||||
* Policy pack signature required to run in “enforced” mode.

## 3) Sovereign Readiness — CryptoProfile + RootPack
|
||||
|
||||
### Objective
|
||||
|
||||
**Drop‑in regional cryptography** (Russia/China/EU/US) with offline operation.
|
||||
|
||||
### CryptoProfile (attached to every signature/attestation)
|
||||
|
||||
```json
|
||||
{
|
||||
"id": "GOST-2012@v1",
|
||||
"algorithms": {"sign":"GOST R 34.10-2012","hash":"GOST R 34.11-2012","cipher":"GOST 34.12-2015"},
|
||||
"key_policy": {"curve":"id-tc26-gost-3410-2012-256","hsm_required": true},
|
||||
"time_stamping": {"tsa": "rootpack://ru/tsa1"},
|
||||
"roots": ["rootpack://ru/trustanchors/gost-ca1"]
|
||||
}
|
||||
```
|
||||
|
||||
### RootPack
|
||||
|
||||
* Tarball containing: trust anchors, intermediate CAs, OCSP/CRL snapshots, TSA profiles, policy constraints (e.g., no cross‑sign with foreign roots), and region metadata.
|
||||
* Installed via: `stella rootpack import rootpack_ru_v1.tar.gz`.
|
||||
|
||||
### Dual‑Signing & Guardrails
|
||||
|
||||
* Policy flags like `allow_dual_signing FIPS+GOST`, `forbid_sm2_for_us_exports` (example only).
|
||||
* Enforcement happens at signing time and verification time.
|
||||
|
||||
### Acceptance Criteria
|
||||
|
||||
* Offline verification using RootPack succeeds; online OCSP disabled per policy.
|
||||
* Mis‑profiled signatures are rejected with explicit reason codes.
|
||||
* Dual‑signed DSSE verifies under both profiles when allowed.
|
||||
|
||||
---
|
||||
|
||||
## 4) Attestation Observability Graph (AOG)
|
||||
|
||||
### Objective
|
||||
|
||||
Make trust **observable**. Expose SLIs/SLOs for cryptographic posture & policy compliance.
|
||||
|
||||
### Data Model
|
||||
|
||||
* Nodes: `{artifact, sbom, policy, vex, srm, signature, rootpack, runtime_instance}`
|
||||
* Edges: `derived_from`, `signed_by`, `evaluated_by`, `replayed_by`, `runs_as`
|
||||
|
||||
### Metrics (OpenTelemetry/Prometheus)
|
||||
|
||||
* `stella_trust_sli{service,env}` = fraction of running pods whose image has a valid SRM‑backed attestation chain under the active policy.
|
||||
* `stella_attestation_latency_seconds` (P50/P95) from build to verified‑ready.
|
||||
* `stella_policy_drift_events_total` (increment when running policy != signed policy).
|
||||
* `stella_exception_without_proof_total` (must be 0).
|
||||
* `stella_replay_success_ratio` (per week).
|
||||
|
||||
**SLO Example**
|
||||
|
||||
* **Trust SLO ≥ 99.9%** measured hourly; error budget resets monthly.
|
||||
|
||||
### Interfaces
|
||||
|
||||
* `stella aog export --format otlp`
|
||||
* `GET /v1/aog/graph?artifactDigest=...` → subgraph JSON (with signed edge proofs).
|
||||
* Grafana dashboards (packaged).
|
||||
|
||||
### Acceptance Criteria
|
||||
|
||||
* AOG can reconstruct the full trust lineage for any running pod in ≤ 2s (p95) on a 1k‑service cluster.
|
||||
* Metrics cardinality bounded (service/env/policy only).
|
||||

|
||||
|
||||
## 5) Procurement‑Grade “Trust Statement”
|
||||
|
||||
### Objective
|
||||
|
||||
One **board‑ready** artifact that unifies security posture across vendors; machine‑readable twin for ERP/GRC.
|
||||
|
||||
### Outputs
|
||||
|
||||
* **PDF** (human): signed, watermark, controlled fields for vendor name/version/date, summary graphs, SLOs, exceptions with PCE (proof‑carrying exceptions).
|
||||
* **JSON** (machine): normalized schema below; DSSE‑signed; includes SRM and policy references.

|
||||
* CLI: `stella trust-statement generate --srm srm.yaml --policy corp-runtime.lattice.json --out acme-1.9.2.trust.json --pdf`.
|
||||
|
||||
### Acceptance Criteria
|
||||
|
||||
* JSON validates against schema; PDF and JSON hashes match the DSSE statement.
|
||||
* ERP ingest POC: Ariba/ServiceNow field mapping validated.

## 6) Third‑Party Proof Channel
|
||||
|
||||
### Objective
|
||||
|
||||
Create a **publisher ecosystem** for upstream proofs: SBOM, VEX, and **VDR (Vulnerability Derivation Reason)**.
|
||||
|
||||
### Publisher Model
|
||||
|
||||
* **Identity:** publishers obtain a **Publisher Certificate** (could be verified via RootPack‑anchored CA or cross‑signed).
|
||||
* **Submission:** `stella ledger publish --type {sbom|vex|vdr} --artifact <digest> --file proof.json --sign`.
|
||||
* **Moderation & Revocation:** CRL‑like **Proof Revocation List (PRL)** with signed reasons.
|
||||
|
||||
### VDR (schema sketch)
|
||||
|
||||
```json
|
||||
{
|
||||
"schema":"vdr.stellaops.dev/v1",
|
||||
"artifact":"sha256:...",
|
||||
"cve":"CVE-2025-12345",
|
||||
"claim":"not_affected",
|
||||
"method":"entrypoint_unreachable|abi_mismatch|dead_code",
|
||||
"evidence_refs":[{"type":"symbol_map","digest":"sha256:..."}],
|
||||
"publisher":"redhat://rhel",
|
||||
"signatures":[...]
|
||||
}
|
||||
```
|
||||
|
||||
### Consumption
|
||||
|
||||
* Policies can **prioritize** publisher channels by trust level.
|
||||
* AOG shows which proofs originated from which publishers.
|
||||
|
||||
### Acceptance Criteria
|
||||
|
||||
* At least one upstream (e.g., base image vendor) can publish and your policy can consume & rank it.
|
||||
* PRL revokes a proof and AOG reflects the change within 5 minutes.

## 7) Zastava — differential SBOM + AI enrichment scheduler
|
||||
|
||||
### Objective
|
||||
|
||||
Produce **entrypoint‑aware differential SBOMs** and continually **re‑enrich** new/old SBOMs with AI context and exposure‑aware prioritization.
|
||||
|
||||
### Concepts
|
||||
|
||||
* **dSBOM:** SBOM that reflects effective dependency set for a specific `ENTRYPOINT/CMD` and runtime flags (e.g., `--server.urls`, `DOTNET_...`).
|
||||
* **Scheduler:** rescans **old SBOMs** when: (a) new CVE feeds arrive, (b) new VEX/VDR appear, (c) policy changes, or (d) AI models learn new exploitability signals.
|
||||
|
||||
### Pipeline
|
||||
|
||||
1. **Static slice:** infer reachable packages from entrypoint (e.g., `.NET Kestrel` vs CLI tool).
|
||||
2. **Runtime slice (optional):** collect process tree, open sockets, and imported modules at startup in a **shadow run** or mirrored traffic.
|
||||
3. **Diff:** `dSBOM = SBOM ∩ (static_reachable ∪ runtime_observed)`.
|
||||
4. **AI Enrichment:** Zastava annotates each finding with *context weights* (exposed/not exposed, network scope, RBAC, secrets proximity).
|
||||
5. **Plan:** produce PRs (Dockerfile base bump, package pin, k8s Service change).
|
||||
6. **Scheduler:**
|
||||
|
||||
* `stella zastava schedule --query 'service=payments AND env=prod' --interval 6h`
|
||||
* Triggers re‑evaluation and emits updated SRM + Trust deltas.
|
||||
|
||||
### dSBOM format (addon)
|
||||
|
||||
```json
|
||||
{
|
||||
"schema":"cyclonedx+stella-diff@1.0",
|
||||
"base_sbom":"sha256:...",
|
||||
"entrypoint": ["/app/bin/Release/net10.0/app.dll"],
|
||||
"cmd": ["--urls","http://127.0.0.1:8080"],
|
||||
"static_reachable": ["pkg:nuget/Kestrel@*", "pkg:nuget/System.Data@*"],
|
||||
"runtime_observed": ["pkg:rpm/openssl@3.0.9"],
|
||||
"excluded_paths": ["/usr/share/docs/**"],
|
||||
"digest":"sha256:..."
|
||||
}
|
||||
```
|
||||
|
||||
### Kestrel example (priority logic)
|
||||
|
||||
* If Kestrel present but Service is `ClusterIP` and no Ingress, **deprioritize**; if `LoadBalancer`/`NodePort` with 0‑RTT TLS disabled, **prioritize**.
|
||||
* Zastava produces an **explainable card**: “Priority lowered due to non‑exposed runtime path; evidence: `kubectl get svc`, `netstat`, policy rule #42.”
|
||||
|
||||
### Acceptance Criteria
|
||||
|
||||
* Changing `ENTRYPOINT` produces a different, signed dSBOM and updated priorities.
|
||||
* Scheduler updates stale SBOMs and issues signed deltas without network access (when RootPacks + feed mirrors are available).
|
||||
|
||||
---
|
||||
|
||||
## Cross‑Cutting Security & Compliance
|
||||
|
||||
* **Sanctions & Guardrails:** per‑profile constraints (e.g., forbid dual‑signing across certain jurisdictions). Policy‑enforced at sign/verify time.
|
||||
* **HSM Integrations:** PKCS#11 providers for each profile (FIPS, GOST, SM2).
|
||||
* **Data handling:** SRMs and Trust Statements may contain paths and hashes; optional redaction profiles for vendor sharing.
|
||||

```
|
||||
|
||||
---
|
||||
|
||||
## Success Metrics (per pillar)
|
||||
|
||||
* **SRM:** ≥ 99% of production images have SRM attached; **Replay Success Ratio** ≥ 0.99 weekly.
|
||||
* **Policy/Lattice:** 100% of exceptions carry proof; policy test coverage ≥ 90% on top CVE classes.
|
||||
* **Sovereign:** RootPacks for RU/CN/EU/US verified; dual‑signing working in CI; offline verification median < 200 ms.
|
||||
* **AOG:** Trust SLO ≥ 99.9%; lineage lookup p95 ≤ 2s.
|
||||
* **Trust Statement:** Accepted by at least one ERP (pilot); generation time ≤ 15s.
|
||||
* **Third‑Party Channel:** ≥ 3 upstream publishers integrated; PRL revocations flow to AOG within 5 minutes.
|
||||
* **Zastava:** dSBOM reduces non‑reachable high/critical findings by ≥ 35% without raising exposure incidents.
|
||||
|
||||
---
|
||||
|
||||
## Risks & Mitigations
|
||||
|
||||
* **Crypto complexity:** profile misuse → strict guardrails + default safe profiles, strong linting.
|
||||
* **Cardinality/telemetry blow‑ups:** AOG label hygiene + sampling.
|
||||
* **Vendor adoption (Proof Channel):** seed with your own base images and internal frameworks; provide SDKs and reference publishers.
|
||||
* **Determinism regressions:** CI runs replay tests on golden SRMs; any drift fails the build.

## Competitive Landscape (Jan 2026)
|
||||
|
||||
Based on source-code audit of Trivy v0.55, Grype v0.80, Snyk CLI v1.1292, plus documentation review of Prisma, Aqua, and Anchore.
|
||||
|
||||
### The Nine Structural Gaps We Exploit
|
||||
|
||||
| # | Capability | Industry Status | Stella Ops Advantage | Module(s) |
|
||||
|---|-----------|-----------------|---------------------|-----------|
|
||||
| 1 | **SBOM Fidelity** | Static artifact, order-dependent, varies per run | Deterministic per-layer digests + Build-ID mapping; binary crosswalk | `Scanner`, `SbomService`, `BinaryIndex` |
|
||||
| 2 | **VEX Handling** | Boolean suppression or absent | K4 lattice (Unknown/True/False/Conflict) with trust weighting | `VexLens`, `TrustLatticeEngine`, `Excititor` |
|
||||
| 3 | **Reachability** | "Runtime context" badge (coarse) | Three-layer call-path proofs (static + binary + runtime) with DSSE | `ReachGraph`, `PathWitnessBuilder` |
|
||||
| 4 | **Backport Detection** | Version string checks | Four-tier: distro feeds → changelog → patches → binary fingerprints | `Feedser`, `SourceIntel`, `BinaryIndex` |
|
||||
| 5 | **Smart-Diff** | File-level/hash comparison | Semantic risk deltas ("exploitability dropped 41%") | `MaterialRiskChangeDetector` |
|
||||
| 6 | **Triage UX** | Loud lists, duplicated root causes | Quiet queue + one finding per root cause + evidence panel | UI + canonical finding keys |
|
||||
| 7 | **Unknowns** | Hidden/suppressed | First-class state with bands, decay, policy budgets | `UnknownStateLedger`, `Policy` |
|
||||
| 8 | **Attestations** | Cosign-only or absent | in-toto/DSSE chain for scans, VEX, reachability, fixes | `Attestor`, `Signer` |
|
||||
| 9 | **Offline** | Partial cache, degraded signals | Full parity with sealed snapshots + regional crypto | `AirGap.Controller`, `CryptoProfile` |
|
||||
|
||||
### Why Competitors Plateau (Architectural)
|
||||
|
||||
| Competitor Class | Origin | Why They Can't Easily Catch Up |
|
||||
|-----------------|--------|-------------------------------|
|
||||
| **Trivy/Syft/Grype** | Package scanners | No forensic reproducibility in architecture; evidence model is row-based, not content-addressed; VEX is filter, not logic |
|
||||
| **Snyk** | Developer UX | SaaS-only means offline impossible; no attestation infrastructure; reachability is language-limited |
|
||||
| **Prisma/Aqua** | Policy/compliance | No deterministic replay; no cryptographic provenance; verdicts aren't portable |
|
||||
| **Anchore** | SBOM operations | No lattice VEX; no signed reachability graphs; no regional crypto profiles |
|
||||
|
||||
### Capability Gap Matrix
|
||||
|
||||
| Capability | Trivy | Grype | Snyk | Prisma | Aqua | Anchore | **Stella** |
|
||||
|-----------|-------|-------|------|--------|------|---------|------------|
|
||||
| Deterministic replay | No | No | No | No | No | No | **Yes** |
|
||||
| VEX lattice (K4) | Boolean | Boolean | None | None | Limited | Limited | **Full** |
|
||||
| Signed reachability | No | No | No | No | No | No | **DSSE** |
|
||||
| Binary backport detection | No | No | No | No | No | No | **Tier 1-4** |
|
||||
| Semantic risk diff | No | No | No | No | No | No | **Yes** |
|
||||
| Unknowns as state | Hidden | Hidden | Hidden | Hidden | Hidden | Hidden | **First-class** |
|
||||
| Regional crypto | No | No | No | No | No | No | **Yes** |
|
||||
| Offline parity | Medium | Medium | No | Strong | Medium | Good | **Full** |
|
||||
|
||||
### Where We're Ahead (Unique)
|
||||
|
||||
1. **Deterministic replay** — Bit-for-bit reproducibility with `stella replay`
|
||||
2. **K4 lattice VEX** — Conflict detection, not suppression
|
||||
3. **Signed reachability** — DSSE graphs + edge bundles
|
||||
4. **Smart-Diff** — Semantic risk deltas
|
||||
5. **Unknowns modeling** — Bands, decay, policy budgets
|
||||
6. **Regional crypto** — FIPS/eIDAS/GOST/SM/PQC as config
|
||||
|
||||
### Where Competitors Lead (For Now)
|
||||
|
||||
| Area | Leader | Our Response |
|
||||
|------|--------|--------------|
|
||||
| Mass-market UX | Snyk | Focus on power users who need proofs |
|
||||
| SaaS onboarding | Snyk, Prisma | Offer both SaaS and self-hosted |
|
||||
| Ecosystem breadth | Trivy | Depth over breadth; evidence quality over coverage |
|
||||
| Marketplace integrations | All | Prioritize based on customer demand |
